Spiral-wound reverse osmosis elements in two groups. Industrial elements are 2540 and 4040 formats (2.5" and 4" diameter, 1 016 mm long) in brackish water, low-energy, low-pressure, ultra-low-pressure and high-flow grades from DuPont FilmTec, DuPont TapTec, Vontron and Ovay, alongside equivalent elements. Residential and light-commercial elements are 1812, 2012, 3012 and 3013 formats rated from 189 to 1 514 L/day. The range also includes an 1812 nanofiltration element and a 4040 ultrafiltration element. Performance figures are each manufacturer's own test conditions, which differ between makers and grades; the test salinity and pressure are stated on each row. Actual output varies with feed water, temperature and recovery.

Match the element to feed TDS and available pressure. Brackish water (BW) elements give the highest rejection on higher-TDS borehole feeds; low-energy (LE), low-pressure (LP) and ultra-low-pressure (ULP) elements deliver similar flow at lower pressure on municipal and low-TDS feeds, at slightly lower rejection. Compare elements only at like test conditions: a rating at 1 500 mg/L and 10.3 bar is not comparable with one at 2 000 mg/L and 15.5 bar. Do not mix element types in one vessel. Pretreat to the element's SDI limit (5 for most elements listed) and free chlorine below 0.1 mg/L; polyamide membranes do not tolerate chlorine. Confirm the element format (1812, 2012, 3012, 3013, 2540 or 4040) against the housing before ordering.

Lead times are indicative estimates only, based on typical supply at time of publication, and are confirmed at order acceptance. They show our usual longest sourcing time. We can often supply sooner from our network of local suppliers. Actual times may vary with supplier stock, manufacturing, importation, customs and logistics. Only a written quotation or order confirmation commits DWT to a delivery time.
